Confusion in Libya over Gaddafi son's fate

As fighters for Libya's National Transitional Council say they're making further inroads into the town of Sirte, there are conflicting reports over the fate of one of Gadaffi's sons.

Some figures from the National Transitional Council told news agencies Mutassim Gaddafi had been seized in the family's embattled hometown of Sirte.

However, officials in the NTC stronghold of Benghazi could not confirm the claims, which have sparked celebratory gunfire in several cities.
